------------------------------
Summary: Make all MockRM#waitForState consistent.
Key: YARN-4907
URL: https://issues.apache.org/jira/browse/YARN-4907
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Yufei Gu
Assignee: Yufei Gu
There are some inconsistencies among these {{waitForState}} in {{MockRM}}:
1. Some return a boolean, some don't.
2. Some have a minimum waiting time(1000ms), some one don't. I appreciate if
someone can explain why we need a minimum waiting time.
3. Some wait function don't have a timeout, they can wait for ever.
4. Some use LOG.info and others use {{System.out.println}} to print messages.
